Routine Maintenance Instructions
• All Bobrick Dryers require cleaning every 6 months to ensure that they function effectively. Please
note that failing to clean the dryer may result in malfunction and can void the warranty.
• If the dryer is installed in an area prone to dust and dirt this cleaning procedure should be carried
out more frequently.
• Check the length of motor brushes, where applicable, when performing the cleaning procedure.
Cleaning Instructions:
a) The Exterior of Cover

permanently damage the surface.
Bobrick dryers are drip proof (IP21 or better, see rating label). DO NOT spray with liquids to an
extent that they could enter the unit.
b) The Interior
Having turned off all power to the dryer, remove the cover.
Using a small brush or vacuum, carefully clean out the build up of dust and lint.
Check the length of the motor brushes. If less than ½'' replace. Check that motor brushes are i
installed correctly and that brushes are worn evenly.
Replace the cover.
Turn the power back on.

To Remove Existing Timer
1. Disconnect the power supply and remove the cover.
2. Remove the timer from the base plate by unscrewing the two screws securing the timer bracket to the base. On recessed
dryers the timer bracket is secured to a metal angle bracket, this bracket with its screws must be removed and retained
for use on the replacement timer.
3. Disconnect the pink or yellow, red, and black timer wires from the terminal block and the white wire push on connector
from the triac (115V only). Place the timer aside for return to the Service Department.
To Install New Timer
1. Mount the timer assembly to the base plate . In the case of recessed dryers, it is rst necessary to attach the metal angle
bracket removed from the faulty timer to the new timer.
2. Route the timer wiring under the element tube and attach the white wire push on connector to the small spade terminal
on the triac (115V only), older 208 – 240V units may have a base plate mounted triac, this is no longer required and can
be removed.
3. Connect the remaining three timer wires to the terminal block, black wire to terminal 1, red wire to terminal 2, pink wire to
terminal 3.
4. Secure wiring with cable ties provided.
5. Replace dryer cover. Switch on electrical supply and test operation.
Installation Of Touch Controller
Warning
Risk of electric
shock
Disconnect power
supply before
removing cover
Note: This procedure applies only to surface-mounted or recessed dryers with triac
mounted on the base plate. For touch button models with triac mounted on the timer
bracket, the complete timer assembly must be replaced.
To Remove Existing Triac
1. Disconnect power supply and remove cover.
2. Remove white, yellow or pink, and black Push On connectors from triac.
3. Remove the two screws securing the triac to the base plate.
4. Remove the triac and place to one side for return to Service Department.
To Install New Triac
Note: On factory-installed triac, a white Heat sink Compound is interposed between the triac ange and the dryer base plate
to ensure rapid conductivity of heat away from the triac. For service purposes this compound is replaced by a thin plastic
gasket of heat conducting material, this must be sandwiched between the ange and the base plate during assembly.
1. Position new triac and pad on base plate with the Terminals positioned as shown in illustration below. Insert and tighten
the two self-threading screws and shake proof washers provided.
2. Attach the white wire Push On connector to the small spade Terminal on the triac. The black wire from the Terminal
Block should then be attached to the next Terminal round in a clockwise direction and the yellow or pink wire to the
remaining Terminal.
3. Replace dryer cover. Switch on electrical supply and test operation, allow 10 seconds for the controller to stabilize be
fore placing hands in front of lens (automatic units).
Installation Of Base Plate Mounted Triac
Warning
Risk of electric
shock
Disconnect power
supply before

Older units have an intermediate plug and socket in the wiring, this has now been discontinued and can be removed with the
faulty controller. The wiring on older units may be sleeved, this was later replaced by plastic cable ties. Some early 115 volt
dryers had 4 way terminal blocks instead of the current 3 way blocks, in these dryers the wires to the 4th terminal should not
be disturbed.
To Remove Control Unit
1. Remove outlet grille from front of fan case by unscrewing the
securing screws.
2. Remove the screws securing the control unit to the base plate.
(Note the different position of recessed and surface-mounted
screws).
3. If the control unit wiring is secured by cable ties, carefully cut
these to free the 4 wires from other wiring.
4. Remove the Push On Terminal securing the white wire to the
triac.
5. Disconnect the controller wires from terminals 1, 2, and 3 on
the terminal block. Leave all other wires in position.
6. Carefully lift control out of base plate. Avoid disturbing other
wiring. (Note: On recessed dryers it will be necessary to slide
the control to the right to clear the fan case).
To Install New Control Unit
1. Position the new control unit on the base plate to line up with
the screw holes and secure with the screws and washers
previously removed.
2. Route wiring under element tube and connect wiring as fol
lows: white wire with Push On Terminal to triac. Black wire to
Terminal 1 (with existing black wire). Red wire to Terminal 2
(with existing red wire). Pink wire to Terminal 3 (with existing
wiring).
3. Secure all wires to existing wires with a minimum of 2 cable
ties.
4. Replace grille and sealing gasket and secure with screws
previously removed.
5. Check all wires for security and all screws for tightness.
6. Replace cover. Switch on electric supply.
7. Allow 10 seconds for the controller to stabilize and check
operation of the dryer. If the operation is intermittent check that
the controller has a clear view out of the cover aperture, use
the spacers provided to raise the controller if required.
